problem with some files that won't sync

[gottdesign]

I have been using Creative Cloud with no problems until recently. I am getting the ! in front of some of my files but not others. Recently, I created a new folder and moved all the ! files into it. Everything was fine. Now I'm getting the ! again, not for all files but for some, the ones I've worked on most recently. The message says "Unable to sync" --- server error.
